DOOR SECURING DEVICE Filed Aug. 4, 1930 (James "(Gear/2W5 ATTO R N EYS UNITED STATES PATENT OFFICE JAMES W. GEARHART, OF FRESNO, CALIFORNIA DOOR SECURING DEVICE.

Application filed August 4, 1930. Serial No. 472,817.

This invention relates to improvements in door securing devices, and has particular ref erence to a portable device, which may be carried in the pocket, for securing a door which may or may not be provided with a lock.

The principal object of this invention is to produce a portable device which may be attached to any door having a latch for the purpose of securing the same against being opened from the outside, defeating the master key, pass key, and the efforts of burglars and unscrupulous persons in picking locks, and also preventing the intrusion of anyone into a hotel, apartment or other room. A further object is to provide means in the formation of the portable device to compensate for various sizes of spaces between the door and door jamb.

A further object is to produce a portable 2 device of this character which is simple in construction, economical to manufacture, highly eflicient in use, and which is durable enough to resist heavy strains.

Other objects and advantages will be ap- 2 parent during the course of the following description. 7

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a perspective view of my device,

Figure 2 is a view similar to, Figure 1, with the device turned on its axis, 180,

Figure 3 is a cross sectional view of the line 33 of Figure 2,

Figure 4 is a cross sectional view on the line ale- 1 of Figure 2,

Figure 5 is a top plan view of my device showing the manner in which the same is applied to the door before the same is closed, and

Figure 6 is a view similar to Figure 5, but

showing the door in closed position, and the device in a securing position.

There are many doors which are not provided with locks,and there are other doors which are provided with locks which may be opened with a master key or pass key or broken away, or easily picked, and it is to accommodate doors of this character that applicant has devised his portable securing device whereby the user may efl'ectively secure the door against opening fromthe outside.

The device is of a portable detachable na- I ture and affords protection to travelers who desire privacy against the entry of persons to a room, or who do not wish to trust themselves or their valuables to the conventional locking devices employed.

In the accompanying drawings wherein for the purpose of illustration is showna preferred embodiment of my'invention, the numeral 5 designates a securing plate having a hooked end 6. At 7 I have shown a lug which is bolted as at 8 or otherwise secured to the plate 5 and through which a rod 9 passes. This rod is threaded as at 11, which threads are adapted to engage threads formed within the lug 7. A knurled head 12 serves to rotate the rod 9, the purpose of which will be later seen. This rod 9 has ro-- tatably secured thereto a slider 13, the cross section of which is channel shaped as shown in Figure 4. This slider is slidably secured to the plate 5 and is provided with a spring 16 the end of which bears against the plate 5 as at 17, (see Figure 3). This action tends to keep the ends of the plate and the slider spaced apart, the purpose of which will later be seen. The slider 13 has a bent end 18 which is adapted to abut one side of the latch casing as is shown in Figure 6. 1

' The manner of using my device is as follows The end 18 is inserted at A, the latch bolt having been withdrawn into the latch by a turn of the door knob. The door is then gently closed until the hooked end 6 engages in the opening B, or door strike or latch receptacle. The door is then completely closed, the end 18 then being in aperture A and the hooked end 6 being in aperture B. As soon as the door has been closed, the knurled head 12 is rotated so that the threads 11 of the rod 9 engage the threads in the lug 7, with the result that due to the action of the spring 16, the two ends 6 and 18 will be held in their proper position. It will now be apparent. that any pressure upon the door from the springimeansinterposed between said slider andsa d plate fonmov'lng the ends of said outside, such as would move the door toward the right of the drawings as shown in Figure 6, will be resisted through the fact that the slider 13 is being rigidly held by the threaded connection between the rod and the lug.

While I have shown a threaded arrangement of the rod 9 to efiect a movement of the slider 13,, itisqobviousgthat a trip or like arrangement niight also be employed to effect an actuation of the slider to thus provide an effective locking operation lot the door securing device. 1

It is to be understood that the-:forrn of my invention herewith shown and described is to be taken as a preferred example ofthe sameand that various.changesrelative to the material size, shape and'iarrangement of piuftSmay be resorted to without departing ffrornzthefspiritfof the invention or the scope 1 5 9f .thfi 11M Oi f d laimsr 7 .Having 'thus described my invention, 1
